Ethics and movie reviewing can be uneasy bedfellows. I think this is mostly because we all start developing tastes well before we start in depth critical thinking about the construction and overall effectiveness of the films we watch. And though all of us may try to fall back on some techniques of objective critique, it can be difficult to apply what you know about film theory to a film like John Mikl Thor's “Rock ‘n’ Roll Nightmare”. That said we all have some thumbnail idea about what makes a film worthy and rules that help us to determine that.
